So your doctor has recommended a sleep study. Maybe you’ve been snoring loudly, waking up exhausted, or your partner has noticed you stop breathing at night. Whatever the reason, a sleep study test is one of the most reliable ways to find out what’s actually happening while you sleep.
But here’s the thing: most people have never done one before. And the idea of sleeping in an unfamiliar place, hooked up to wires, can feel strange. A little preparation goes a long way in making the experience comfortable and ensuring accurate results.
What is a Sleep Study?
A sleep study, also called polysomnography, is a diagnostic test that monitors your body while you sleep. It records brain activity, eye movements, heart rate, breathing patterns, oxygen levels, and muscle activity. This data helps doctors identify disorders like obstructive sleep apnea, restless leg syndrome, narcolepsy, and other conditions that disrupt rest.
What is polysomnography exactly? It’s simply the technical term for this overnight monitoring. A PSG sleep study captures detailed information that can’t be gathered any other way certainly not by guessing or relying on how tired you feel.
The test typically takes place at a sleep clinic or sleep laboratory, though home sleep study options are now available for certain conditions, particularly suspected OSA sleep study cases.

Types of Sleep Studies
Not all sleep tests are the same. Your doctor will recommend the one that fits your situation:
In-Lab Polysomnography: This is the gold standard. You spend a night at a sleep lab where technicians monitor you using specialised equipment. A polysomnography test measures everything from brain waves to leg movements. If you’re searching for a sleep study test or polysomnography test, your doctor can refer you to an accredited facility.
Home Sleep Test: A home sleep test or sleep apnea test at home uses a portable device to measure breathing, oxygen levels, and heart rate while you sleep in your own bed. It’s simpler than in-lab testing but works best for diagnosing obstructive sleep apnea in otherwise healthy adults. A sleep study test at home won’t capture as much data as a lab study, but it’s more convenient and often more affordable.
CPAP Titration Study: If you’ve already been diagnosed with sleep apnea, a CPAP test helps determine the right air pressure settings for your therapy device.
Snoring Test and Sleep Apnea Test: These may be part of a broader sleep disorder test or conducted as standalone evaluations when snoring is the primary concern.
How to Prepare: Before Your Sleep Study
Preparation matters. The goal is to sleep as naturally as possible so the results reflect your actual sleep patterns.
- Talk to Your Doctor About Medications
Discuss all medications and supplements you’re taking, including over-the-counter ones. Some medications affect sleep architecture and could skew results. Don’t stop or change anything without your doctor’s guidance. If you struggle with insomnia or anxiety about the test, your doctor may prescribe something to help you relax. - Avoid Caffeine and Alcohol
On the day of your study, skip caffeine after noon. That means coffee, tea, chocolate, and energy drinks. Caffeine can linger in your system for hours and make it harder to fall asleep. - Alcohol should also be avoided in the afternoon and evening. While it might make you drowsy initially, alcohol fragments sleep and can mask or worsen certain disorders, especially sleep apnea.
- Skip the Nap
As tempting as it might be, don’t nap on the day of your sleep test. You want to be tired enough to fall asleep at the lab. Arriving well-rested could mean hours of lying awake, which doesn’t help anyone. - Avoid Hair Products
Here’s one people often forget: don’t use hair gel, oil, or spray on the day of the test. Electrodes need to be attached to your scalp to measure brain activity, and products create a barrier that interferes with the signal. The same goes for heavy lotions or makeup.

What to Pack for an In-Lab Sleep Study
If you’re heading to a sleep laboratory, pack like you’re staying at a hotel overnight:
- Comfortable pyjamas or sleep clothes
- Toiletries (toothbrush, toothpaste, face wash)
- A change of clothes for the morning
- Any medications your doctor has approved
- Your CPAP machine and mask, if you already use one
- A book or something relaxing to help wind down
- Your own pillow, if that helps you sleep better
Most sleep clinics provide private rooms with their own bathrooms. The environment is designed to feel less clinical and more like a bedroom, though admittedly with more wires.
What Happens During the Sleep Study?
You’ll arrive at the sleep clinic in the evening, usually a couple of hours before your normal bedtime. A technician will explain the process, ask about your sleep habits, and may have you fill out a questionnaire.
Then comes the setup. Small sensors called electrodes are attached to your scalp, face, chest, and legs using a mild adhesive. These connect to a sleep test machine that records data throughout the night. A small clip on your finger monitors oxygen levels. It sounds like a lot, but most people adjust quickly.
You’ll have time to read, relax, and prepare for bed. When you’re ready, the lights go off and the monitoring begins.
What if I can’t fall asleep?
Sleeping in a new environment with sensors attached isn’t exactly natural. But nearly everyone eventually drifts off, even if it takes longer than usual. A valid polysomnography test only requires about two hours of sleep, so don’t stress if you toss and turn initially.
What if I need to use the bathroom?
There’s a microphone in the room, and a technician can disconnect you temporarily. This happens all the time, especially for people with sleep apnea who often wake to urinate.

After the Sleep Study
In the morning, the sensors are removed, and you’re free to go. Most people head straight to work or continue their normal routine.
Sleep study test results are typically reviewed by a sleep specialist and sent to your referring doctor within a few days to a couple of weeks. The report will detail your sleep stages, breathing events, oxygen levels, and any abnormal movements or behaviours.
If a disorder like obstructive sleep apnea is confirmed, your doctor will discuss treatment options ranging from lifestyle changes and positional therapy to CPAP machines or oral appliances.
Sleep Study Cost: What to Expect
Sleep study cost varies depending on the type of test and where it’s conducted. An in-lab polysomnography cost is generally higher than a home sleep test due to the facility, equipment, and staffing involved.
If you’re researching sleep study test cost or sleep study test price, it’s worth checking whether your insurance covers diagnostic sleep testing, many plans do, especially when ordered by a physician.
